An Improved Scheme of Frequency-Dependent AVO Inversion Method and Its Application for Tight Gas Reservoirs

Figure 2

The prestacked synthetics at different incidence angles for layered medium model. The peak at 0.1 s coincides with the interface across the top two elastic nonreservoir layers. The trough at 0.2 s coincides with the interface between the elastic nonreservoir and poroelastic gas-reservoir layers.
